3、框架添加
// 网络请求框架
compile project(':okhttp3')
//
compile project(':library')
// 注解开发
compile 'com.jakewharton:butterknife:8.4.0'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0'
compile 'com.android.support:design:26.1.0'
compile 'com.android.support:cardview-v7:26.1.0'
compile 'com.android.support:recyclerview-v7:26.1.0'
// Dialog对话框
compile 'com.flyco.dialog:FlycoDialog_Lib:1.2.6@aar'
compile 'com.nineoldandroids:library:2.4.0'
compile 'com.google.code.gson:gson:2.8.1'
// litepal数据库操作
compile 'org.litepal.android:core:1.6.0'
4、初始化
//1、用到litepal数据库需要在App初始化操作
LitePal.initialize(this);
//2、Okhttp初始化
private void okhttpint(){
String downloadFileDir = Environment.getExternalStorageDirectory().getPath()+"/okHttp_download/";
String cacheDir = Environment.getExternalStorageDirectory().getPath()+"/okHttp_cache";
OkHttpUtil.init(this)
.setConnectTimeout(15)//连接超时时间
.setWriteTimeout(15)//写超时时间
.setReadTimeout(15)//读超时时间
.setMaxCacheSize(10 * 1024 * 1024)//缓存空间大小
.setCacheType(CacheType.FORCE_NETWORK)//缓存类型
.setHttpLogTAG("HttpLog")//设置请求日志标识
.setIsGzip(false)//Gzip压缩，需要服务端支持
.setShowHttpLog(true)//显示请求日志
.setShowLifecycleLog(false)//显示Activity销毁日志
.setRetryOnConnectionFailure(false)//失败后不自动重连
.setCachedDir(new File(cacheDir))//设置缓存目录
.setDownloadFileDir(downloadFileDir)//文件下载保存目录
.setResponseEncoding(Encoding.UTF_8)//设置全局的服务器响应编码
.setRequestEncoding(Encoding.UTF_8)//设置全局的请求参数编码
//.setHttpsCertificate("12306.cer")//设置全局Https证书
//.addResultInterceptor(HttpInterceptor.ResultInterceptor)//请求结果拦截器
//.addExceptionInterceptor(HttpInterceptor.ExceptionInterceptor)//请求链路异常拦截器
.setCookieJar(new PersistentCookieJar(new SetCookieCache(), new SharedPrefsCookiePersistor(this)))//持久化cookie
.build();
}
5、项目根目录拷贝文件
image.png
6、settings.gradle 添加
include ':app', ':library', ':okhttp3'
7、添加样式
<style name="loading_dialog_style" parent="android:Theme.Dialog">
<item name="android:windowFrame">@null</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:backgroundDimAmount">0.4</item>
</style>
<style name="circleProgressBarStyle">
<item name="android:indeterminateDrawable">@drawable/rotate_loading_icon</item>
<item name="android:indeterminateDuration">1500</item>
</style>
